IMPROVEMENT IN CAR- COUPLINGS.

Specification formingpart of Letters Patent No. 178,787, dated June 13,1876; application filed May 10, 1876.

To all whom it may concern:

Be it known that I, REUBEN LooMrs, of Geneseo, in the county ofLivingston and State of New York, have invented certain new and usefulImprovements on Gar-Couplings; and I do hereby declare the following tobe a full, clear, and exact description thereof, ref' erence being hadto the accompanying drawing, and to the letters of reference markedthereon.

The nature of my invention consists in the construction and arrangementof a car-coupling, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertaius to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichforms a part of this specification, and in which- Figure 1 is aperspective view of my carcoupling. Fig. 2 is a longitudinal section ofthe same. Fig. 3 is a detailed section of a part thereof.

A and B represent the two cast-iron drawheads, attached in any ordinarymanner to opposite ends of railroad-cars;

In the draw-head A is fastened, by a bolt, 1), a wrought-iron loop orlink, 0, that connects the cars, said link being held in a wroughtironclevis, D, to'the end of which is attached a spiral spring, a, to holdthe loop or link level.

E E are two side springs, near the outer end of the draw-head A, to holdthe loop 0 in the center, so that when the cars come together the loopwill enter the opposite draw-head and be fastened there.

The clevis D is secured in the draw-head A by a horizontal bolt, d, theends of which pass into vertical slots 6 in the sides of the drawhead.These slots are elongated vertically to allow the bolt d, that holds theclevis, to rise,

so as to depress the end of the loop O that is to be attached to thenext car, so as to couple to a car that is lower than the one to whichthe clevis is attached. By the construction of the clevis the outer endof the loop can be elevated, to couple with a car that is higher.

In the top of the draw-head A is a slot, f, so that the clevis and loopcan be raised when the cars are uncoupled, and the loop can be turned toone side when it is desired to push having it couple to another car.

This guide-box A is cast whole, except one side, which is cast separate,and fastened to the other part by'bolts and screws, and can be taken offwhen necessary for any purpose.

The opposite draw-head B is cast whole, except the top piece, which iscast separate, and is fastened to the main part by bolts and screws.under the top piece, is a wrought-iron yoke, G, working in slots in thesides of the head, to which yoke is attached the pin I, that passesthrough the loop 0, and holds it when the cars are coupled. The loop, onentering this draw-head, pushes the bottom of the pin I back, so as tolet the pin through the loop, and the spiral springs h, on the outsideof the draw head, attached to the yoke, pull the bottom of the pinforward, thus bringing it down through the loop, and the loop andsprings hold it fast.

Behind the pin I the interior of the drawhead B is .beveled on bothsides to guide the loop, so that the pin will never fail to enter theloop.

On the inside of the top piece to this drawhead B is cut out a space, t,to let the pin and yoke turn up, so that it will never fail to uncouple.

In the. bottom of the draw-head is a slot, m, to prevent the pincatching on the bottom at the time of coupling.

On each end of the yoke of the draw-head, is a crank, 10, to which thespiral spring his connected; and these cranks are, by rods 8, connectedto crank-shafts J J, mounted in hearings on the end of the car, wherebythe cars may be uncoupled from either side without going in between thecars.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

l. The clevis D, connected in the draw-head A by a horizontal bolt, (1,passing into vertical slots 0 e in the sides of the draw-head, andhaving the coupling link or loop 0, fastened therein by the bolt b, asand for the purposes herein set forth.

2. The combination of the draw-head B,

having recess *& and slot m, as described, the

the car onto a switch or elsewhere without Across the top of thisdraw-head,

G, on the outside yoke G, with pin I, cranks p, and springs h, Intestimony that I claim the foregoing I all substantially as and for thepurposes herehave hereunto set my hand this 6th day of i in set forth.March, 1876.

3. The combination, in a car-coupling, of p the draw-head A, havinglongitudinal slot f REUBEN LOOMIS. and slots 6 e, the elevis D, springa, link or e i i i loop 0, secured by bolt b, and the side springsWitnesses: E E, all constructed substantially as and for W. H. KELSEY,the purposes set forth. J OHN R. STRONG.
